Defect induced magnetism in SiC Interplay between ferromagnetism and paramagnetism

open access: yes, 2015
Defect-induced ferromagnetism has triggered a lot of investigations and controversies. The major issue is that the induced ferromagnetic signal is so weak that it can be sufficiently accounted for by trace contamination. To resolve this issue, we studied
